TS1105/06 Data Sheet TS1105 and TS1106 Unidirectional and Bidirectional Current- KEY FEATURES Sense Amplifiers + Buffered Unipolar Output with Adjustable Bias Low Supply Current The TS1105 and TS1106 combine the TS1100 or TS1101 current-sense amplifiers with Current Sense Amplifier: 0.68 A a unipolar buffered output featuring adjustable bias. I : 0.76 A VDD The TS1105 and TS1106 high-side current-sense amplifiers consume 0.68 A (typ) and High-Side Bidirectional and Unidirectional Buffered Current Sense Amplifiers 1.2 A (max) of supply current while the buffered output consumes 0.76 A (typ) and 1.3 A (max) of supply current. With an input offset voltage of 100 V (max) and a gain error Wide CSA Input Common Mode Range: +2 V to +27 V of 0.6% (max), the TS1105 and TS1106 are optimized for high-precision current meas- urements. Low CSA Input Offset Voltage: 100 V (max) Applications Low Gain Error: 0.6% (max) Power Management Systems Two Gain Options Available: Portable/Battery-Powered Systems Gain = 20 V/V: TS1105-20 and TS1106-20 Smart Chargers Gain = 200 V/V: TS1105-200 and Battery Monitoring TS1106-200 Overcurrent and Undercurrent Detection 8-Pin TDFN Packaging (3 mm x 3 mm) Remote Sensing Industrial Controls silabs.com Smart.
